The results of studying the effect central metal ion on stability gadolinium and holmium complexes with 1,10'-phenanthroline-2,9-dicarboxylic acid diamide are presented. obtained values constants turned out to be an order magnitude lower than previously known for these elements 4,7-dichloro-1,10'-phenanthroline-2,9-dicarboxylic diamide. Keywords: spectrophotometry, gadolinium, holmium, contrast...

Trihexyltetradecylphosphonium (P6,6,6,14) salts of luminescent anionic Pt(II) complexes, (P6,6,6,14)[PtX2(ppy)] (X = Cl-, Br-; ppy 2-phenylpyridinate), are synthesized and photofunctional thin films with crystal/liquid bi-stability fabricated. In particular, the chloride complex provides a film exhibiting thermo- mechano-triggered luminescence ON/OFF switching at ambient temperature, which is b...

Tris(2-pyridyl)borates are introduced as a new robust and tunable "scorpionate"-type ligand family. A facile synthesis of this hitherto unknown ligand and its complexation to Fe(II) are described; the optical and electrochemical properties of the resulting iron complex are compared to complexes derived from tris(pyrazolyl)borate, tris(2-pyridyl)aluminate, and corresponding charge-neutral ligands.

A method is described for the determination of organochlorine pesticide residues in human gallstones. The difficulty caused by the presence of large amounts of cholesterol in the stones is overcome by an acetylation step in the “clean-up” procedure, and the method finishes with identification and determination of the individual pesticides by gas-liquid chromatography. Results are given for 28 s...

This review highlights several in vivo studies utilizing non-genotoxic and genotoxic chemical carcinogens, and the mechanisms of their high and low dose carcinogenicities with respect to formation of oxidative stress. Here, we survey the examples and discuss possible mechanisms of hormetic effects with cytochrome P450 inducers, such as phenobarbital, a-benzene hexachloride and 1,1-bis(p-chlorop...

The syntheses and characterization of both tris(diethylamino)aluminum and tris(diisopropylamino)aluminum are presented in this letter. Characterization includes vapor pressure measurements and comparison of the two non-pyrophoric precursors showing them to be viable alternatives to trimethylaluminum. Ultimately, tris(diisopropyl)aluminum was successful in the atomic layer deposition of alumina ...
